Re: [rmcat] NADA Implementation in Mozilla

[Sergio Garcia Murillo <[e-mail]>]

Hi Xiaoqing and Sergio,

Great to see you are still working on it.

I proposed a while back the use of a common logging format for being 
able to create tools for measuring the performance and comparing the 
behavior of the different bwe algorithms:

https://github.com/medooze/bwe-stats-viewer

Would you consider adding support to it on your source code? If you are 
still using the transport wide cc feedback messages the information 
dumped would be quite straight forward.

Also, it would be interesting knowing how did you perform the testing 
scenarios and if we could create a set of scripts to replicate them 
easily, what do you think?

Best regards
Sergio
